NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY NEGATIVE ELECTRODE MATERIAL, NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY NEGATIVE ELECTRODE INCLUDING THE NEGATIVE ELECTRODE MATERIAL AND NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY INCLUDING THE NEGATIVE ELECTRODE

Abstract:

An object is to provide a non-aqueous electrolyte secondary battery negative electrode material which can improve a battery life as compared with a conventional one, a non-aqueous electrolyte secondary battery negative electrode including such a negative electrode material and a non-aqueous electrolyte secondary battery including such a negative electrode. A non-aqueous electrolyte secondary battery negative electrode material that includes a negative electrode active material formed of a silicon-based material a skeleton-forming agent including a silicate having a siloxane bond and an interface layer formed in an interface between the negative electrode active material and the skeleton-forming agent and formed of an inorganic material, a non-aqueous electrolyte secondary battery negative electrode including it and a non-aqueous electrolyte secondary battery are provided.
